Compiler Warnings by compiler version (Compilerwarnungen nach Compilerversion)

Mit der Compileroption /Wv kann der Compiler Warnungen unterdrücken, die nach einer von Ihnen angegebenen Version eingeführt wurden. Diese Option eignet sich zum Verwalten des Buildprozesses, wenn Sie eine neue Toolsetversion einführen und neue Warnungen vorübergehend unterdrücken möchten. Diese Option unterdrückt nur Warnungen, keine neuen Fehlermeldungen. Unterdrücken Sie nicht alle neuen Warnungen dauerhaft! Es wird empfohlen, immer auf der höchsten regulären Warnstufe (/W4) zu kompilieren und die Option /Wv aus Ihrem Build zu entfernen, sobald dies praktikabel ist.

In diesen Versionen des Compilers wurden neue Warnungen eingeführt:

Sie können nur die Hauptversionsnummer, die Haupt- und Nebenversionsnummer oder die Hauptversions-, Nebenversions- und Buildnummer für die Option /Wv angeben. Der Compiler meldet alle Warnungen, die mit Versionen übereinstimmen, die mit der angegebenen Zahl beginnen. Alle Warnungen für Versionen, die größer als die angegebene Zahl sind, werden unterdrückt. Beispielsweise meldet /Wv:17 Warnungen, die in oder vor einer Version von Visual Studio 2012 eingeführt wurden, und unterdrückt Warnungen, die von einem Compiler ab Visual Studio 2013 (Version 18) oder höher eingeführt wurden. Um Warnungen zu unterdrücken, die in Visual Studio 2015 Update 2 und höher eingeführt wurden, können Sie /Wv:19.00.23506 verwenden. Verwenden Sie /Wv:19.11, um die Warnungen zu melden, die in einer beliebigen Version von Visual Studio vor Visual Studio 2017, Version 15.5, eingeführt wurden, aber Warnungen zu unterdrücken, die in Visual Studio 2017, Version 15.5 und höher, eingeführt wurden.

In den folgenden Abschnitten werden die Warnungen aufgeführt, die von jeder Version von Visual C++ eingeführt wurden und die Sie mithilfe der Compileroption /Wv unterdrücken können. Die Option /Wv kann keine Warnungen unterdrücken, die nicht aufgeführt sind und die vor den angegebenen Versionen des Compilers liegen.

C5245	„function“: Eine nicht referenzierte Funktion mit interner Verknüpfung wurde entfernt.
C5246	„member“: Die Initialisierung eines Teilobjekts muss in geschweifte Klammern eingeschlossen werden.
